Missing available directives in the Redis configuration for RDB in redis chart

Name and Version

bitnami/redis 20.6.1

What is the problem this feature will solve?

Tried to configure RDB feature in helm chart.
Looks like directives are missing to set configuration from values files.

In the Redis cluster chart, these directives exist.

For example: Link

Is there any other way to configure RDB with possible configurations and disable AOF?

What is the feature you are proposing to solve the problem?

Options for RDB:

stop-writes-on-bgsave-error:
rdbcompression: 
rdbchecksum:
dbfilename:
save:
dir:

I would like to clarify first.

In redis chart
Currently commonConfiguration directive includes only save and appendonly options. Link
And redis.conf only contains these two configurations.

From redis-cluster chart
We can see that redis-default.conf is written from official website.

I would like to apply same logic here also. Write default redis configuration. and overwrite if user is defined custom one.

1. Remove commonConfiguration
2. Create default redis.conf from official website.
3. Add defaultConfigOverride to redis values as in redis-cluster chart.
4. In configmap.tpl check defaultConfigOverride.

Yes, that’s expected since, ultimately, both Helm charts are distinct products. The logic may differ as features are implemented based on user feedback or to address specific use cases. Similarly, we often receive contributions from users that apply changes to a specific Helm chart (e.g., Redis standalone) but are not extended to others (e.g., Redis Cluster).

If you have changes in mind, feel free to submit a PR. The team would be happy to review your contribution!
